Abstract (en)

[origin: WO2018197001A1] A method (100) for determining if an amount of deposition of scale, on a heating element (1) arranged for heating a liquid in a heating space (3) of a household appliance (5), exceeds a reference amount of deposition of scale or not is provided. The method (100) comprises: measuring (101) temperature (T) of the heating element (1), obtaining (103) a start temperature (T0) of the heating element (1) corresponding to a liquid start temperature (T0L) of the liquid in the heating space (), turning on (105) the heating element (1) at first point in time (t1) to heat the liquid from the liquid start temperature (T0L) and simultaneously starting measuring a time interval (tint) from the first point in time (t1), monitoring (107), at a second point in time (t2), a behaviour (TBE) of the measured temperature (T) of the heating element (1) during heating of the liquid in the heating space () in order to determine if a boiling temperature of the liquid has been reached or not, wherein the time interval (tint) is measured to the second point in time (t2), comparing (109) the measured time interval (tint) with a reference heating duration (trd) required for heating the liquid from the liquid start temperature (T0L) to the boiling temperature of the liquid when heated by a reference heating element having the reference amount of deposition of scale and determining (111) if the amount of deposition of scale on the heating element (1) exceeds the reference amount of deposition of scale or not based on the monitoring (107) and on the comparison (109). Further, a household appliance (3) comprising a heating element (1) is provided.
